Well it depends on what is your plan with your trade. If you invest it for long term then I think you shouldnt be worrying it. If day trader then apparently within the. I usually take profit if it hits 5-7%. This will be a more realistic target. Search for a volatile coin and have a good volume so that you can get out easily. For midterm I think 20-30% is sufficient enough but if I am anticipating news that may give a big impact to the coin then I just set a stop loss then if it gets higher then I just adjust my stop loss. As they always say have a trading plan before entering any trade.
but for this you need to have a good patience in order to expect a better moment. If you chose such a project, which is sure about 100%, then everything should turn out without the slightest problems. But How to choose the best investment in the market?
Why dont we need to be worry if we invest long term? Long term also has very high risk so please dont deny it.
We need to worry about both investment, long and short. With our worry, we are expected to becareful with our decision.
